SPECIFICATION forming part of Letters Patent No. 422,776, dated March.4, 1890.

Application filed September 30, 1889. derial No. 825,536. (No model.)

To ctZZ whom, it may concern:

Be it known that I, JAMES F. HATFIELD, a citizen of the United States,and a resident of Dublin, in the county of Wayne and State ofIndiana,have invented certain new and useful Improvements inGrain-Separators; and I do declare thefollowing to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it ap pertains to make and use the same, referencebeing had to th e'aocompanyin g drawings, and

to letters of reference marked thereon, which form a part of thisspecification.

Figure I of the drawings is a representation of a side view of theseparator, illustrating the invention as also in dotted lines the secondposition of the upper shoe-lever. Fig. 2 is a view of the opposite sideof the separator. Fig. 3 is a longitudinal section, and Figs. 4: and 5are details.

This invention relates to certain improvements in grainseparators; andit consists of the novel combination and construction of parts, as willfully appear from the following description and accompanyingillustrations.

In the embodiment of my invention I employ a closure or casin g A, whichis suitably supported in position upon legs or standards Ct Ct,disposing in one end of said closure in the upper part a rotary fan B,which is suitably driven.

C is an inclined upper shoe carrying a sieve C, and having one endarranged under the usual hopper D, secured at its ends to and betweenuprights a, fastened to and project ing upward from the casing orclosure A. This screen or sieve has a smooth upper and is preferably ofzinc, and to effect a separation of the grain from oats and white caps,a smooth endwise movement is imparted to This is obtained by" employingin connection with the actuating mechanism presently described) of theshoe a right-angle) lever D, connecting or pivoting its lower end to theclosure or casing and providing a pivotal connection, as at 7), betweenit and the shoe in alignment with the lower pivot. In this treatment ofthe grain the oats and white caps slide over and out of the sieve orscreen away from the grain, from the grain, however, an up and down Inthe removal of chaff.

extension cl of the shoe C, and fulcrumed, as

at cl, upon the side of the casing or closure A, the low er end of saidlever having connection with a pitman 6, connected to an eccentric c 011the end of the fan-shaft. This mechanism is for actuating the sieve orscreen car-' rying shoe 0.

F is a lower shoe, which has an opposite in clination to the upper shoeC and carries a series of sieves or screens F F 1 for the fur thertreatment of. the grain. This shoe has opposite downwardly extendingarms or pendants f, connected thereto a short distance in ward from itslower end, and pivoted near their lower ends it may be to downward. extensions of the hopper supporting uprights a. These arms or pendants mayhave a common pivot by employing a rod f extending through them andsecured or bearing in the uprights. This shoe also has connection. withand is actuated by the lever D.

Arranged so as to stand a short distance be low the shoe F are bracketsG G, which are adjustably connected to the inner sides of the closuresupporting standards or legs a a to vary the distance between the latterand the shoe. It will be observed that as the shoe F is actuated throughthe lever D it will, by the aid of its pivoted pendants or arms f andthe brackets G, against which it strikes, be rocked up and down from endto end through the jarring motion imparted to the shoe, and screens willdislodge any adhering grain and thus liberate it, permitting the wholeof the grain to pass out of the screens. The screens or sieves F F F arestair steps in length, their rear ends terminating successively oneinward from the other,'and discharge, respect ively, intoa series ofchutes or spouts g g 9 arranged in the rear lower end of the shoe F. Thechaff is carried off into the trunk h, at the rear end of the casing,the bottom of which. inclines from. the center laterally in twodirections. At the base of each incline of the bottom of the trunk. h isa discharging opening or outlet h for the contents thereof.

Instead of causing the lower shoe to carry the grain receiving anddischarging chutes or spouts as heretofore, which puts that much moreweight on the gearing or actuating mechanism, I provide a supplementalshoe H for carrying the spouts or chutes, designated at 71 and impartavibratory motion to said shoe by connecting it, through pitmen or rodsh with the lower ends of the pendants or arms f, dislodgingany possibleadhering. grain therein,

I is a rod, one provided for each sieve or 1. In a grain-separator orfanning-mill, the combination, with the upper or top screenshoe and itsactuating mechanism, of-the rightangle lever having changeableconnections with said shoe, one at its upper end and the other at itsangle, the lower end of said lever having a fixedpivotal connection withthe "closure or casing, substantially as set forth.
